7.4 MOTLoad Commands
CPCI-6115 CompactPCI Single Board Computer supports two types of commands
(applications): utilities and tests. Both types of commands are invoked from the CPCI-6115
CompactPCI Single Board Computer command line in a similar fashion. Beyond that, CPCI-
6115 CompactPCI Single Board Computer utilities and CPCI-6115 CompactPCI Single Board
Computer tests are distinctly different.
7.5 MOTLoad Utility Applications
The definition of a MOTLoad utility application is very broad. Simply stated, it is considered a
MOTLoad command, if it is not a MOTLoad test. Typically, MOTLoad utility applications are
applications that aid the user in some way (that is, they do something useful). From the
perspective of MOTLoad, examples of utility applications are: configuration, data/status
displays, data manipulation, help routines, data/status monitors, etc.
Operationally, MOTLoad utility applications differ from MOTLoad test applications in several
ways:
z Only one utility application operates at any given time (that is, multiple utility applications
can not be executing concurrently).
z Utility applications may interact with the user. Most test applications do not.
7.6 MOTLoad Tests
A MOTLoad test application determines whether or not the hardware meets a given standard.
Test applications are validation tests. Validation is conformance to a specification. Most
MOTLoad tests are designed to directly validate the functionality of a specific SBC subsystem
or component. These tests validate the operation of such SBC modules as: dynamic memory,
external cache, NVRAM, real time clock, etc.
All MOTLoad tests are designed to validate functionality with minimum user interaction. Once
launched, most MOTLoad tests operate automatically without any user interaction. There are a
few tests where the functionality being validated requires user interaction (that is, switch tests,
interactive plug-in hardware modules, etc.). Most MOTLoad test results (error-data/status-data)
are logged, not printed. All MOTLoad tests/commands have complete and separate
descriptions. Refer to the MOTLoad Firmware Package User’s Manual for this information.
All devices that are available to MOTLoad for validation/verification testing are represented by
a unique device path string. Most MOTLoad tests require the operator to specify a test device
at the MOTLoad command line when invoking the test.
A listing of all device path strings can be displayed through the devShow command. If an SBC
device does not have a device path string, it is not supported by MOTLoad and cannot be
directly tested. There are a few exceptions to the device path string requirement, like testing
RAM, which is not considered a true device and can be directly tested without a device path
string. Refer to the devShow command description page in the MOTLoad Firmware Package
User’s Manual.
